BOBBIN-WINDER.

SPECIFICATION forming part of Letters Patent No. 474,187, dated May3,1892.

Application filed January 20, 1892- Seriul No. 418,686. (No model.) I

To aZZ whom it may concern;

Be it known that I, JOHN 13. PRICE, a citizen of the United States,residing at WVollaston, in the county of Norfolk and State ofMassachusetts, have invented certain new and useful Improvements inBobbin-\Vinders; and I do hereby declare the following to be a full,clear, and exact description ofthe invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in automatic bobbin -winders forsewingmachines; and the object is to provide a simple device adapted towind threads of different sizes which can be readily operated andadjusted.

WVith these and other ends in view my invention contemplates a pulley, aspindle carrying a friction-roller arranged in contact with the pulleyand adapted to be adjusted on the spindle, and devices intermediate ofthe spindle and a traversing-arm to give to the latter the desiredreciprocating movement; and the invention further consists in thecombination of devices and construction and arrangement ofparts, as willbe hereinafter fully described and claimed.

To enable others to more readily understand my invention, I haveillustrated the same in the accompanying drawings, in which- 1 Figure 1is a side elevation, partly in section. Fig. 2 is a sectional viewshowing a modification of the means for adjusting the device to windthreads of difierent sizes. Fig.

3 is a sectional view on the lineoc 0c of Fig. 2.

Fig. 4: is a side View of the pulley with the circles thereon. Fig. 5 isa side elevation, partly in section, showing a slightly-modifiedconstruction; and Fig. 6 is a bottom plan view of Fig. 5.

Referring to the drawings, in which like letters of reference denotecorresponding parts in all the figures,A designates the frame,which isconstructed as shown in the drawings and as hereinafter referred to. Thepulley B, to which motion is communicated from the machine by the usualbelt, is secured on a horizontal shaft 19, extending entirely throughthe frame and having a step or bearing 6 at its inner end to receivethebobbin. The bobbinis held in place by the usual spring-pressed arborjournaled in the opposite end of the frame, and the shaft 1) is somewhatlonger than its bearing in the frame, so that when the bobbin is inplace the arbor will be forced against the-bearing b by its spring andthe pulley B also brought into contact with the friction-roller; butwhen the bobbin is removed the shaft will move endwise in its bearing torelease the pulley from contact with the friction-roller, so that thefriction-band on said roller will not become flattened.

The spindle C is provided with a worm screw-thread at its lower end. Theupper end is fitted to rotate in a soc'kctc of an arm 0 of the frame,while its other end is stepped in tacts one end of a lever e, which isconnectedby intermediate devices with the traversing arm to give to thesame the proper reciprocating movement.

To communicate the motion of the pulley B to the traversing arm throughthe mechanism above described, I provide a frictionroller F, which issecured on the spindle so as to be capable of an adjustmentlongitudinally thereof and radially to the driving-pulley, and saidroller is provided with an annular groove f to receive an elasticfriction-ring f, which is adapted to contact with the face of thepulley. This face of the pulley is inscribed with a series of concentriccircles a, by which the movement of the traversing arm is regulatedaccording to the size or diameter of the cotton or thread to be wound.This is accomplished by simply adjusting the friction-roller 011 thespindle, so that the fric- I tion-band will contact with the face of thepulley near to or remote from the axis of the same and 011 the lineindicated by a particular circle, according as the grade of the cottonis coarse or fine. It is obvious that in the a A j tion and adaptationthe device can wind threads of different grades in a proper andeffective manner and maintain in each 1n- -stance a uniform tension onthe thread and a relative distributionof the thread on the bobbin. Thefriction-roller may be secured on the spindle by a key or feather, asshown in Fig. 1, in which case the key is loosened to permit the rollerto be adjusted and tightened' to retain the same in place; or it may befastened by the device illustrated in Figs. 2 and 3, which I will nowdescribe.

The hollow threaded spindle 0 extends entirely through its bearing inthe arm 0 of the frame, and it is secured in place at its lower end by apin G, which passes through a frame and is locked in a groove g in thelower end of said spindle, or the adjusting-screw cl (illustrated inFig. 1) may be employed, as desired. Within this spindle O is a threadedadjusting-rod I-I, having a thumb-nut h on its upper end just above thehollow spindle, and it is held therein by a pin h, driven through thespindle and locked into a groove h on the lower end of the screw. Thefriction-roller F is arranged on the spindle in the usual manner and isadapted to actuate the same when in contact with the pulley. The spindlehas a slot I extending throughout its length, and a threaded gib t",carried by the friction-roller, is adapted to contact with the threadedadj usting-rod H through the slot I. The friction-roller F is secured onthe spindle in a practically rigid position, and the gib z" is supportedloosely on said roller, the screw turning with the spindle. When it isdesired to adjust the friction-roller to adapt the device for adifferent grade of thread,'the nut h isturned to rotate theadjusting-rod H, and the gib t", carried by the friction-roller andarranged in contact with said screw through the slot in the spindle,will move the roller to the desired position as said screw is turned.

The lever e, which is actuated by the cam e, is arranged in engagementwith the traversing arm J and moves the same back and forth, accordingas it is actuated by the cam. A springj presses against said traversingarm and holds the lever in engagement with the face of the cam, and Ialso provide an adjusting-screw j on the end of the lever, which isarranged in engagement with the cam. The connection between the leverandtraversing arm may be of various forms, and I have shown in Fig. 1 atoothed segment K on said lever arranged to mesh with a similar segment76 on the traversing arm. Instead of using the segments K Zr, I mayconstruct the lever e asshown in Figs. 5 and 6, which is a much simplerform.

I am aware that changes in the form and proportion of parts and detailsof construction may be made without departing from the spirit orsacrificing the advantages of my inventionas, for instance, the lowerend of the spindle may be provided with cog-teeth L to engage with agear-wheel, as Eand I therefore reserve the rightto make such changes asfall within the scope of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is
